You are playing the "ww2 european map". am i right? You have two choises you have to change the pediaicons text or you have to change the "ww2 european map" file. but i think that you have saves game going so do this. Open the pediaicons.txt in the text file. Use search to find where in the text is this text "#TECH_Amphibious_Warfare" when you find it change it to this "#TECH_Amphibious_War" dont change anything else then search this text "#TECH_Amphibious_Warfare_LARGE" and change it to this "#TECH_Amphibious_War_LARGE". If you want to start a new game you can do this. open the "ww2 european map" file and under the rules take edit rules and there Civilization advances and search the "Amphibious War" and change it to "Amphibious Warfare". If you use this second one you cant play our saved game. That fix the bug but if it didnt go away,but another message here.
